Container (10) is generally cylindrical except for a longitudinal concave groove (11) extending along its entire length. Upon explosion, the contour of this groove (11) results in a focussing effect on the wall material due to the oblique angle at which the expanding cylindrical detonation wave front impacts upon its inner wall. This produces the forging of a rough rod-like projectile (111) which, being coherent, maintains its velocity and consequently travels much further than the randomly shaped projectiles (101).

1. An explosive charge comprising a tubular container, said container being generally square shaped and containing an explosive material within said container, said container consisting of four walls, said four walls being equally radially spaced, said container consisting of four web-portion wall portions, said walls being linked by said web-portion wall portions, each of said four walls being a concave longitudinal flute of substantially uniform thickness, each of said flutes being straight and each of said flutes having a longitudinal axis substantially parallel to the longitudinal axis of said tubular container, each of said concave longitudinal flutes extending along substantially the entire length of said container and upon detonation of said explosive material, each of said flutes producing a coherent linear projectile, said linear projectiles providing a cutting effect applied in four equally spaced directions. 2. The charge according to claim 1, wherein said web-portion wall portions are rounded. 3. The charge according to claim 1, wherein said concave longitudinal flutes are rounded grooves. 4. The charge according to claim 1, wherein said concave longitudinal flutes each have a mid-line and are each symmetrical to said mid-line. 5. The charge according to claim 1, wherein said longitudinal flutes have a contour that, upon detonation, produce a focusing effect such that most of the material forming said longitudinal flutes form said coherent linear projectiles. 6. The charge according to claim 1, wherein the tubular container is formed from a material selected from the group consisting of plastic, ceramic, aluminium, magnesium, zirconium, and alloys of aluminium, magnesium and zirconium. 7. A linear explosively formed projectile charge for producing projectiles, the charge comprising an elongate casing being generally square shaped and having a compartment portion containing explosive material, said elongate casing consisting of four equally radially spaced longitudinal flutes which extend along substantially the entire length of said elongate casing, said flutes having substantially uniform thickness and being approximately spherical or hyperbolic, said elongate casing consisting of four web-portion flute portions, said flutes being linked by said web-portion flute portions, each of said flutes producing coherent linear explosively formed projectiles upon detonation of said explosive material, whereby in use no jet is formed in said coherent linear projectiles. 8. A tubular charge comprising a container, said container being generally square-shaped and containing an explosive material within said container, said container consisting of four concave longitudinal flutes which extend along substantially the entire length of said container, each of the concave longitudinal flutes having wall material of substantially uniform thickness, said container consisting of four web-portion flute portions, said flutes being linked by said web-portion flute portions, and upon detonation of said explosive material, each of the flutes forming a coherent linear projectile in which about 90% of the wall material in each of said flutes constitutes each said linear projectile. 9. A tubular container configured to hold an explosive material within said tubular container for use in an explosive charge, said tubular container consisting of four walls, said four walls being equally radially spaced, said container consisting of four web-portion wall portions, said walls being linked by said web-portion wall portions, each of said four walls being a concave longitudinal flute of substantially uniform thickness, each of said flutes being straight and each of said flutes having a longitudinal axis substantially parallel to the longitudinal axis of said tubular container, each of said concave longitudinal flutes extending along substantially the entire length of said container, each of said flutes being configured to produce a coherent linear projectile upon detonation of explosive material within said tubular container.
